I got tired of finding themes that almost fit my taste, so I finally decided to make my own by combining my favorite elements of a few different themes. The theme is mainly based on Glow (http://gnome-look.org/content/show.php/Glow?content=85996), but the scrollbars are from Gloss, and a few other things are from a few other themes...
I also included the Glow metacity theme and a modified version of the emerald theme.
The icon theme "Wise" from GNOME-colors (http://gnome-look.org/content/show.php/GNOME-colors?content=82562) fits very nicely.
Note: This theme requires the Aurora and Clearlooks engines.
